LAM P-STOVE.

SPECIFICATION forming part of Letters Patent No. 411,209, datedSeptember 17, 1889.

Application filed November 16, 1888- Serial No. 291,012- (No model.)

To all whom it may concern.-

Be it known that l, \VILLIAM H. lVILDER, a citizen of the United Statesof America, residing at Gardner, in the county of \Vorcester and Stateof Massachusetts, have invented certain new and useful Improvements inLamp-Stoves, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My objects are generally to reduce the nu 1nber of parts, to cheapen themanufacture, to insure durability, and to produce a simple and salablearticle.

It is desirable in lamp-stoves to provide lighting-openings of thelargest size possible consistent with preserving the strength of thechimney. Heretofore it has been the practice to cut out a portion of thechimney directly in the center of the front and to form the seam at theside or end. This construction is objectionable for two reasonsnamely,the front side is weakened by the cutting away of the central portionandonly a limited amount of metal can be removed, and the seams at theends detract from the looks of the stove. The chimney as constructed byme consists of a sheet of metal having openings formed near each end forreceiving the mica, said sheet being bent into proper elongated form andunited by its interlocking ends centrally of the front. Another featureof my lampstove lies in utilizing the chimney as the whole connectingand holding means for the cone and the top grate, dispensing withscrews, pins, and the like. I have devised a special form of removableleg adapted particularly to stoves of this character in which a tank isused, said leg being secured to the tank at or near the lower portionthereof and having an upward extension lying along in front of the tankside, which extension is held at its upper end to the tank andpreferably to the top thereof.

In the drawings, Figure 1 is a perspective view of the entire stove,looking from the front. Fig. 2 is a central vertical section through thestove, a portion of the chimney being broken away. Fig. 3 is ahorizontal section through the chimney on line a: a: of Fig. 2, the tankbeing shown in plan. Fig. 3

is a plan View of the under side of the end of the cone-plate, showingthe manner of bending the end edge of the chimney. Fig. 4 is an endelevation of the stove, the top grate and part of the chimney and tankbeing in section. Fig. 5 is a detail sectional View of thesupporting-leg and tank. Fig. 6 is a detail bottom view of the tankcorner and leg.

A is the tank, composed of the bottom portion a and the top a, each ofwhich is of cast metal. The cone-rest B is supported by the front legsI) b, one of which is located at each end of the same, and bya centralback leg Z), the foot 12 of which rests upon and is secured by a screw 1to the tank-cover. On each side of this leg are the bearing-sockets 2 2,which receive the angular projections 3 3 of the cone C. Theseprojections act as pivotal bearingpoints, by which the cone with thechimney and the top grate may be tilted when desired. The cone is heldat the front of the cone-rest by the spring-catch 4 on the cone engagingwith a lip 5 on the cone-rest. The rear leg I) is held by a singlescrew, as before stated, and when this is secured the whole upper partof the stove is supported on and fastened to the tank, the front legsmerely bearing on the tank-top. This arrangement of supporting-legsallows the hinges and catch to be conveniently positioned withoutinterference. The filling-aperture is located at the rear in one corner,as at 6. The whole arrangement is such that the front of the lamp isleft clear and unobstructed. The handle J is also located at the rear,and the screw which secures the rear central leg to the tank-top alsofastens the handle. The lower end of the handle fits in a recess, Fig.4, formed in the back of the tank, and is thus held against lateralmovement, while the upper end lies upon the foot of the central leg andis held by the screw. The formation of the tank with the recess alsoserves another useful function besides holding the lower end of thehandle, in that a flange or lip b is thus provided extending inwardlyfrom the rear edge of the tank, and the lip receives the screw whichholds the handle and all the upper parts. It will be obvious that werethe screw seated in the upper edge of the tank it would be so near theedge that breakage would easily occur. By the lip, however, the screwhas a firm bearing without weakening the joint.

The chimney is formed of sheet metal bent into elongated form withrounded ends. In making this part of the article I aim to provide largeopenings in the front for the emis sion of light without impairing thestrength of the chimney. For this purpose the seam D, which unites theends of the sheet metal, is made tocome directly in the center of thefront, while the openings for the mica are lo- .cated upon each side ofthis central seam.

The seam acts as a 'supp0rting-post, and being formed of fourthicknesses of metal it supplies any deficiency in strength which mightarise from the cutting out of the metal.

As will be seen, the mica extends practically all the way across thefront of the chimney, and light is thus derived from end to end of theflame. The central seam, besides adding strength where it is mostdesired, presents, in connection with the cut-out portions, anornamental appearance. The mica is held by the frames d d, which arepunched out of the sheet-metal chimney and forced to the front, beingintact with the chimney at points 7.

In order to accomplish my object more fully regarding the reduction ofthe article to the simplest construction, I aim to make the chimneyanswer as the sole support and holder for the top grate, and also thesole means of connection and attachment between the said top grate andthe cone. The top grate is composed of the upper bars 8 and a plate 9 ofelongated form, which is connected with the upper bars by means of arms10, it being understood that the bars, the plate, and arms are all castin one piece. The plate 9 has a flange 11 extending along the front andrear and in a plane slightly above the bottom of the plate, thus forminga bearing for the upper part of the chimney, which when in place restsagainst the edge 12 of the plate and serves to support the same by meansof the flange 11, which rests upon it.

Projections 13 are provided at the front and rear of the plate, whichextend below the edge of the chimney and thus serve to retain the samein place against outward movement; and it will be noticed, also, thattendency to inward movement under the pressure of the article beingheated is resisted by the edge of the plate. The grate is held bybending the upper edge of the chimney at the ends over the projectingends of the plate 9, as shown in Figs. 1 and 2. This has been found tobe a highly eifective mode of fastening the grate and chimney together.It does away with screws, pins, or the like, and obviates the necessityof drilling or other work, which is a decided advantage in articles ofthis character intended for household use and consequently to be placedupon the market at a low figure. It will be noticed that the regular andsymmetrical countour of the chimney is described. The chimney is thesame height at the ends as at other points, and in order to allow thebending to be done the ends 13 of the plate 9 are bent downwardslightly, so

that the edges adjacent to the ends of the chimney are somewhat belowthe plane thereof and the metal can be easily turned over. The edges ofthe chimney at the ends may project all slightly upward in order toattain the same end as regards bending without bending down the ends ofthe plate 9. The chimney rests upon the horizontal cone-plate, with itslower edge abutting squarely thereupon, and for the purpose ofconnecting the chimney the upwardly-extending walls of the cone areprovided with slots a little above the plane of the horizontalcone-plate, so that the connection can be effectively completed bysimply bending inwardly the end edge 3/, Figs. 2 and 3, of the chimneyat these points. Curved ribs 21 are formed on the cone-plate, and thechimney-edge fits between these and the wall of the cone. The bending ofthe edge of the chimney is done from beneath the cone-plate, and theribs serve to cover the slots in the cones and the ends of the chimney.It will be noticed that this arrangement avoids the use of projectingtongues, as the slots are above the plane of the lower edge, and thereis no waste of material. The grate resting directly upon the edge of thechimney and the latter bearing with its edge squarely against. thehorizontal cone-plate make a strong construction, as the pressure of theweight is directly down and in a line coincident with the chimney-walls.

I now come to the special form of leg which is particularly adapted tobe used in combination with a lamp-stove.

The tank is cast with projections E at each lower corner, whichordinarily answer the purpose of feet. These projections are notched, asat cl, to receive screw-pins, as hereinafter described. The leg F hasanupper portion 6, adapted to lie along the side of the tank and to hookover or engage with the cover by means of the hooked end 6', adapted tofit the rib f, formed on the cover. At a point adjacent to the loweredge of the tank the leg broadens out and is provided on its inner sidewith projections g g, which go under the tank on either side of thesmall projections E. From this point the leg inclines outwardly to thefoot 6 the hooked end engaging with the cover and the projectionsengaging with the bottom of the tank constituting the supporting partsof the leg, and in order to draw the said leg into position I employascrew G, which passes through the leg and the notch d of the projectionE, where it is held byanut 7L. The hooked upper end of the leg servesalso the purpose of securing the cover and aids in resisting strainingor separating of the cover and tank.

\Vhile I have shown the tank top or cover as madeseparate from the body,it will be understood that it is only necessary for the success of thisportion of my invention that the leg engage or fit over the upper edgeof the tank or over the top, whether it be separate from or integralwith the body, which connection avoids the use of additional securingmeans at this point, such as screws, pins, or bolts.

I claim as my invention- 1. In a lamp-stove, the tank, the top grate,the chimney formed of sheet metal bent into elongated form and havingthe lighting-opening extending approximately all the way across thefront or from end to end of the wick, said chimney bein united at thecenter of the front, forming a seam intermediate of thelightingopenings, which serve to support the top grate, substantially asdescribed.

2. In combination, thehorizontal cone-plate having the cone proj ectin gupward therefrom, the chimney having its lower edge resting upon thecone-plate, the said cone being formed with slots in itsu'pWardly-extending wall above the surface of the cone-plate and thesaid chimney having a portion of its edge bent therein, substantially asdescribed.
